How to move an existing Line shape in java using a mouse?
I would like to drag a selected line, but I'm unsure how to do it.
I tried the following but it doesn't work and the line doesn't move correctly. What calculations am I missing?
var deltaX = mouseEvent.x - (line.startX + line.endX)
var deltaY = mouseEvent.y - (line.startY + line.endY)
line.startX = line.startX + deltaX
line.startY = line.startY +deltaY
line.endX = line.endX + deltaX
line.endY = line.endX +deltaY
